Energy storing molecule

_G___9. The anaerobic process of splitting glucose and forming two molecules of pyruvic acid

I. ATP

__F__ 10. This starts the process of photosynthesis

J. Kreb’s cycle

__B__ 11. This process does not require sunlight.

K. Glucose

__E__ 12. The pigment that traps sunlight

L. Autotrophs

Directions: Answer each of the following questions in a clear and concise manner. 1. Compare and discuss how cells store energy and release energy using ATP. Be specific! You may draw the cycle.

ATP IS THE ENERGY STORING MOLECULE. THE ENERGY IS STORED IN THE BONDS OF THE 2ND & 3RD PHOSPHATE. WHEN THE BOND IN BROKEN BETWEEN THE 2ND & 3RD PHOSPHATE ENERGY IS RELEASED. ATP IS NOW ADP. T O GET BACK TO ATP ALL THAT HAS TO HAPPEN IS THAT A PHOSPHATE IS BONDED TO THE 2ND PHOSPHATE ON ADP

2. Compare lactic acid fermentation and alcoholic fermentation by describing what pyruvic acid is changed in to. Be sure to include what type of organism each one takes place in. What is pyruvic acid changed into?

Alcoholic Fermentation

Lactic Acid Fermentation

Organism:

ETHYL ALCOHOL

YEAST & BACTERIA

LACTIC ACID

ANIMALS/HUMANS

3. Name the three processes of aerobic cellular respiration. How many ATP’s does each process produce, and what is the total ATP produced from one glucose? 3 Processes of Cellular Respiration:

# ATP produced:

2 GLYCOLYSIS KREBS CYCLE

2

ELECTRON TRANSPORT CHAIN

28 - 34

Total ATP =___30-38 ATP_______

4. Name the two stages of photosynthesis and list the starting molecule(s) and ending molecule(s) of each. Stages LIGHT DEPENDENT REACTION

Starting Molecule(s) LIGHT & H2O LIGHT SPLITS H2O KEEPING THE HYRDOGENS HYDROGENS + CO2

Product(s) O2 IS RELEASED & THE HYDROGENS ARE TAKEN TO THE NEXT STEP C6H12O6

LIGHT INDEPENDENT REACTION

5. What is the general chemical equation of photosynthesis? WATER + CARBDON DIOXIDE + LIGHT  SUGAR + OXYGEN H2O + CO2  C6H12O6 + O2

6. When and why does our body use lactic acid fermentation? 2

LACTIC ACIDS FERMENTATION OCCURS DURING STRENUOUS EXERCISE WHEN NOT ENOUGH OXYGEN IS AVAILABLE FOR YOUR MUSCLE CELLS TO USE TO CREATE ATP

7. Explain how the equations for photosynthesis and cellular respiration compare. THEY ARE BASICALLY THE SAME FORMULA BUT MIRROR IMAGES OF EACH OTHER. WHAT GOES INTO ONE PROCESS IS WHAT COMES OUT OF THE OTHER. WATER & CARBON DIOXIDE GO INTO PHOTOSYNTHESIS AND WATER AND CARBON DIOXIDE COME OUT OF CELLULAR RESPIRATION.
